Battery testing in manufacturing is a multifaceted process that addresses various levels of the battery system. Understanding the nuances of testing battery cells, modules, packs, and BMUs is crucial for ensuring product quality, performance, and safety.
Voltage testing is a fundamental step in battery manufacturing to ensure the quality, performance, and safety of the batteries produced and it covers a lot of ground in battery manufacturing. It is important to measure the open circuit voltage (OCV) of the battery, which is the voltage when there is no load or current flowing.
To analyse the root causes of detects of LiBs, battery safety testing has been developed. They are designed to recreate an abusive environment that represents a cell during an accident.
Overcharging and thermal abuse testing remains the most documented battery safety tests in the literature and the most observed reasons for battery safety accidents.
Voltage testing may also include measuring the battery's voltage while it is under a specific load. This test helps assess the battery's ability to maintain a stable voltage during operation, which is essential for the reliable performance of the battery in its intended application.
Current testing helps determine the battery's capacity, which is its ability to store and deliver energy. By discharging the battery at a specified current rate, the test measures the time it takes for the battery to reach a specific voltage cutoff.
